Instruction:Given two equations write a sequence of steps to solve them.

Input: Equation 1: 2x + y = 4
Equation 2: y + x = 3


assistant
Steps to solve: 
1. Subtract x from both sides of equation 1: 2x + y = 4 → 2x = 4 - y 
2. Subtract y from both sides of equation 2: y + x = 3 → x = 3 - y 
3. Substitute x from equation 2 into equation 1: 2x = 4 - y → 2(3 - y) = 4 - y
4. Simplify: 6 - 2y = 4 - y 
5. Add 2y to both sides: 6 = 2y + y
6. Simplify: 6 = 3y
7. Divide both sides by 3: y = 2 
8. Substitute y into equation 2: x = 3 - 2 = 1 
Therefore, x = 1, y = 2.
